We show that the more central … minority agents are in the social network, the more they assimilate to the majority culture. We also show that denser networks … tend to favor assimilation so that, for example, it is easier to assimilate in a complete network than in a star …

A new model of strategic networking is developed and analyzed, where an agent’s investment in links is nonspecific. The … statics results for Nash equilibria with respect to investment costs for supermodular as well as submodular networking games …. Finally, we provide a broad spectrum of applications from social interaction to industrial organization. …

In such contexts, the patterns of strategic interaction differ from the … network of social relations, as agents display strategic substitution with distance-two neighbors. We show that behavior is …

This paper analyses a simultaneous game of network formation and information acquisition where the benefit structure is … such that the benefit that an agent derives from the network she is located in depends on the maximum information that … someone in her neighbourhood, including herself, acquires. It turns out that in equilibrium star network emerges as the unique …

This paper proposes new centrality measures to characterise the 'key class', when agents in a network are sorted into … role-equivalent classes, such that its removal results in an optimal change in the network activity. The notion of role … theoretical applicability. Players in the network engage in a non-cooperative game with local payoff complementarities. We …
